Keys to choosing the best image sensor
While reviewing the full specification for an industrial image sensor can seem daunting, understanding a few basic parameters can greatly help in matching an image sensor and industrial camera to a given application. This whitepaper provides an overview of some key image sensor specifications and operating modes to help guide users in this process.
Machine Vision Camera Sensor Attributes Explained
Once the general machine vision camera sensor requirements for a specific application are clear, how does one choose among competing camera models and sensors which appear similar - but in fact may have important differences? This whitepaper makes sensor performance characteristics accessible, clarifying concepts like sensitivity, various forms of noise, dynamic range, signal to nose ratio, and more.
3D Time-of-Flight (ToF) sensors for machine vision
Three-dimensional (3D) imaging is used in many different industries ranging from industrial pick and place, palletization/depalletization, warehouse, robotics and metrology applications to consumer-based products such as drones, safety and security, and patient monitoring applications. No one specific type of 3D technology can solve all these different types of applications and the features of each must be compared as to their suitability for each application.
There are a number of different standardized interfaces by which a camera may be controlled by a computer host, and through which images are delivered to the host.

A Guide to Key Considerations in Machine Vision Lens Selection
Improper selection of a machine vision lens can make your camera selection useless – or severely under-performant. Besides the camera sensor and the lighting, the lens is a huge determinant of machine vision outcomes, so it’s well worth understanding enough about lens selection to make informed choices. We survey 10 key questions – and a couple of supplemental concepts – to consider when making a lens selection.
